摘　　要：The ligand effects have been extensively investigated in Au and Ag nanoclusters,while corresponding research efforts focusing on Cu nanoclusters remain relatively insufficient.Such a scarcity could primarily be attributed to the inherent instability of Cu nanoclusters relative to their Au/Ag analogues.In this work,we report the controllable preparation and structural determination of a hydride-containing Cu28 nanocluster with a chemical formula of Cu_(28)H_(10)(SPh^(p)OMe)_(18)(DPPOE)_(3).The combination of Cu_(28)H_(10)(SPh^(p)OMe)_(18)(DPPOE)_(3)and previously reported Cu_(28)H_(10)(SPh^(o)Me)_(18)(TPP)_(3)constructs a structure-correlated cluster pair with comparable structures and properties.Accordingly,the ligand effects in directing the geometric structures and physicochemical properties(including optical absorptions and catalytic activities towards the selected hydrogenation)of copper nanoclusters were analyzed.Overall,this work presents a structure-correlated Cu_(28)pair that enables the atomic-level under-standing of ligand effects on the structures and properties of metal nanoclusters.
